The video is everywhere on Twitter if you're eager to see it. 
A video purporting to show the beheading of British hostage Alan Henning has been released by Islamic State militants.
The Salford taxi driver was delivering aid to Syria in December when he was kidnapped then held hostage by IS.
IS had threatened to kill the 47-year-old in footage showing the killing of Briton David Haines last month.
The UK Foreign Office said it was trying to verify the video, and if true it was a "further disgusting murder".
Prime Minister David Cameron said: "The brutal murder of Alan Henning by Isil [IS] shows how barbaric and repulsive these terrorists are...
"We will do all we can to hunt down these murderers and bring them to justice."
He said his thoughts were with the family of Mr Henning, who had gone to Syria to "help people of all faiths in their hour of need".
Mr Henning's wife Barbara had this week appealed for his release, saying: "He is innocent."
I
S has previously released videos showing the apparent beheadings of two US journalists James Foley and Steven Sotloff, and British aid worker Mr Haines.
The video released on Friday is yet to be verified, but it appears to show Mr Henning kneeling beside a militant, dressed in black, in a desert setting.
The footage ends with an IS fighter threatening a man they identify as an American.
'British accent'
BBC security correspondent Gordon Corera said the video was similar to previous ones released by IS, though slightly shorter.
He said it included a reference to last week's vote by UK Parliament to authorise air strikes against IS in Iraq.
Like previous videos it features a militant with an apparently British accent, he added.
The UK Foreign Office said in a statement: "We are aware of the video and are working urgently to verify the contents.
"If true, this is a further disgusting murder.
"We are offering the family every support possible; they ask to be left alone at this time."
This is the second british nikka they killed right?
